UK DVSAVariation to electrical resistance in the blower regulator wiring harness connector
Risk: Over time irregularities in the crimp connection in conjunction with relative movements of the tin coated connector at the end of the wiring harness which connects to the tin coated blower regulator pin could lead to frictional corrosion. In combination with very high current flow which would occur which could lead to a temperature increase. As a result the blower regulator wiring could be damaged and could lead to partial contact of individual wire strands. this could result in an irregular current flow further overheating and increase the risk of fire.
Fix: The blower regulator wiring harness will be inspected and a new part will be installed.
UK DVSAPlug in contact cable may malfunction
Risk: It is possible that the connection between the B+ cable and the Power Distribution Box can become damaged by wear and heat which is caused by high current flow and high contact resistance. Normally this will result in a non-start situation after parking the vehicle. However it is possible that this could in extreme cases occur whilst the vehicle is in motion. The driver should be made aware of the issue by flickering of the instrument cluster (dash) or an engine mis-fire; but if the driver does not then the engine could cut-out without warning.
Fix: Recall all affected vehicles with petrol engines and replace the cable/connection with a more robust item.
UK DVSAPower steering may not perform correctly
Risk: The electrical contact of the Electronic Control Unit (ECU) of the Electric Power Steering (EPS) is not sufficiently robust over the service life of the vehicle. As a result the power steering support may fail possibly leading to disconcerting driving situation for the driver. Additionally in a few cases a localised thermal event cannot be excluded.
Fix: Recall the vehicles that are likely to be affected and replace the steering gear (EPS).
UK DVSAEngine emergency mode may be activated during driving
Risk: The screws retaining the variable camshaft timing (VANOS) housing may loosen and under certain circumstances the heads may break off.

The inner film on the central display console that shows navigation, multimedia and other information detached and made the display unreadable.
INCIDENT SUMMARY: On January 9, 2026, at approximately 1:30 PM, while traveling at 50 MPH in North Carolina, the vehicle experienced a sudden, catastrophic engine seizure without any prior "Limp Mode" warning or Check Engine Light. This resulted in an immediate, total loss of motive power in active traffic. I was forced to navigate a dead multi-ton vehicle across lanes without power steering or vacuum-assisted braking, narrowly avoiding a high-speed collision. TIMELINE & NEGLIGENCE: This vehicle was purchased from an independent retail dealer on December 20, 2025—less than 21 days prior to…
While traveling at night on the toll road between Washington, DC and Pittsburgh, PA, the vehicle suddenly shut off without warning. Power was lost completely, including power steering, while in motion on a major freeway, creating an immediate and severe risk of collision for us and surrounding motorists. Although the vehicle did restart, it stalled again shortly afterward while still on the toll road. The failure repeated when decelerating on the highway or coming to a stop after exiting. At no point were there warning lamps, check-engine lights, messages, or reduced-power mode indicators…
Dealer refused to cover DME that failed immediately after recall 24V-608 work. In early June 2025, I contacted my local BMW dealership about an overheat notification I received while driving. They confirmed there was an open recall on the vehicle for a water pump connector (Recall 24V-608). I had the vehicle towed to their location. They sent me a video walkaround that characterized everything looked good, except the water pump connector which had failed. Several days later, I was informed the recall repair had been completed but when they plugged in the new water pump connector, the DME…
I discovered suspected non-OEM electrical components, including a twisted white wire pair and burgundy connector, routed through the passenger-side fuse box and terminating at a footwell speaker or unknown transducer. RF scans (TinySA) showed consistent emissions at 93–106.6 MHz in the cabin, even with the engine off. Symptoms include localized EM exposure targeting genital area, neurological disorientation, and floorboard vibration. Vehicle appears modified to emit or transmit RF signals through concealed hardware. No such system is listed in OEM wiring diagrams. BMW dealership and…
The contact owns a 2012 BMW 328I. The contact stated that while starting the vehicle, the engine overheated, with a message that the engine was overheating displayed. The contact stated that while driving at an undisclosed speed, the vehicle stalled with the same message displayed. The vehicle was able to restart. The vehicle was towed to an independent mechanic, where the vehicle was not diagnosed or repaired. The vehicle was taken to the dealer, where it was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 172,000.
My car lost power. It would come and go. Now it's gone. The codes that come up pertain to the wheel speed sensor and timing.
The contact owns a 2012 BMW 328I. The contact stated while driving at an undisclosed speed, the vehicle shuddered and stalled. The contact stated that the vehicle vibrated, and the brakes were independently activated. Additionally, the contact stated that the “Service Required” warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact stated that recently the transfer case was replaced by an independent mechanic. The manufacturer was made aware of the failure. The failure mileage was 110,000.
Yesterday morning 3/24/24 , car stalled on highway with Fuel Pump message on dashboard. Car would not start and had to be towed.
While driving with a passenger in front passenger seat, I occasionally receive a warning that there is a malfunction in passenger restraint system. At that time, the "pass airbag off" light goes on. I took the car to the dealer and was told it is likely a faulty passenger airbag seat occupancy sensor mat. The car is available for inspection. Our safety is potentially compromised because the passenger airbag may not go off in an accident.
Passenger restraint system malfunction. My vehicle as well as thousands of others have the chronic and unsafe issue of the passenger occupancy sensor malfunctioning. In order to remove warning on dash it’s either a $2,000 repair, or a $40 bypass which basically places the seat as constantly occupied, sticking the passenger airbag in the ‘on’ position. Vehicle is available for inspection. With this malfunction, any person that sits in the passenger front seat is at risk of injury or death in the event of a collision. Malfunction has been confirmed by both a dealer and an independent service…

To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
